Will an EcoFlow DELTA 2 Max run a diesel air heater? (EU 230 V)
Yes, it runs it — no usable-capacity figure see why below ↓
Every check passes. What this page will not do is turn a nameplate watt-hour rating into hours — see the evidence below for why.
Official spec + Derived by WattPairverified 2026-08-01EU 230 V unit × diesel air heater
Running34 Wof2,400 Wcontinuous output
0 – 2,400 W across the rails above
No start-up rail: this start lasts minutes rather than milliseconds, so it was checked against continuous output rather than against a surge rating.
Two numbers decide this, and readers use them interchangeably: watts are the ceiling on what the inverter holds at any instant, watt-hours are how much energy the battery holds. A machine can have plenty of one and not enough of the other.
The verdict is a calculation, not a lookup. What it will not do is print a runtime, and the reason is specific: we have found no published depth of discharge or inverter efficiency for the EU 230 V build, so there is no usable-capacity figure to divide.
Where those numbers come from
A blank is never left blank. A field we have found no figure for says so, and a field whose sources disagree — two documents, or one document with itself — says that instead of picking one.
No usable-capacity figure for this machine
EcoFlow states a nameplate watt-hour number for it, and we have found no published depth of discharge or inverter efficiency for the EU 230 V build. Dividing the nameplate by this load would be wrong by 20–35% in the flattering direction, so this page shows the nameplate for what it is and refuses to turn it into hours.
Missing: station.usable_capacity_wh
Energy rate instead of a runtime
34 Wh per hour averaged over this load’s duty cycleThis number needs no battery figure at all, which is why this page can give it when it cannot give hours. Divide any usable-capacity figure you trust by it and you have your own runtime, with our arithmetic visible instead of hidden.
What a diesel air heater demands
No surge rating covers this one, so the engine did not use one: the start-up load lasts 60 seconds rather than milliseconds, and a demand of that length is checked against CONTINUOUS output, where a load that long belongs. That check is the one in the panel above.
Start-up figure Manufacturer-stated
The start-up figure is published by the manufacturer for this device, so it describes the actual hardware rather than a category.

If this is not the pairing
BLUETTI Elite 30 V2 (EU 230 V) reaches the same conclusion on a diesel air heater at 600 W continuous, and it is €219. Cheaper is only cheaper when the answer is the same — this one is. See that pairing →
